EXTENSION-CHANDELIER.

SPECIFICATION forming part of Letters Patent No. 321,506, dated July 7, 1885.

Application filed October 1` 1884. (No model.)

T0 @ZZ whom t may concern.-

Be it known that I, .Iosnrn KINTZ, of Ballard Vale, in the county of Essex, of the Gommonwealth of Massachusetts, have invented a new and useful Improvement in Extension Chandeliers or Lamp-Holders; and I do hereby declare the same to be described in the following specification and represented in the accompanying drawings, of which- Figure '.1 is a front elevation, Fig. 2 a longitudinal section, and Fig. 3 a transverse section, of a chandelier extension-body provided with my invention, the nature of which is deined in the claims hereinafter presented. Figs. et and 5 are inner side views of its notched jaws. Fig. 6 is a front view of the actuator of the said jaws.

The extension chandelier or lamp-holder consists of a slotted tube, a rod or tube to slide lengthwise within the said tube, a stud or projection from such rod or tube, two melallic jaws or strips of metal, each having a series of notches of like kind, number, and size in its inner edge, and mechanism for moving such strips or jaws either toward or away from each other in alateral direction, all being substantially as hereinafter explained, to enable the rod or tube provided with the stud or projection to be slid lengthwise within the outer or slotted tube, and fixed thereto at different distances from its lower end, the outer tube being intended to have iixed to it a series of brackets or arms for supporting candles or lamps, while the inner tube or rod is secured at its upper end to or depends from a ceiling.

In the said drawings, A and B are two tubes, the rst of which extends longitudinally within the other. The outer tube, B, has a slot, a., in it, which 'terminates near each end of the tube, and there extends from the inner tube, A, into such slot a stud or the head b of a screw, C, that is screwed transversely into the tube.

1Within the tube B, and partially encompassing the tube A, are two bars, D D, in the edge or" each of which-that is, next to the slot c-is a series of semicircular notches, c, they being arranged at equal distances apart, and those of one bar being directly opposite those of the other.

Each notch has a dia-meter corresponding to that of the head Z) of the screw G. Each bar D is a long and thin strip of plate metal. It is held within the tube by caps as y at the ends thereof'. Between the said two curved bars is the actuator E, which is another long strip ot metal, connected at the lower end to a slider, F, arranged within a tubular neck, G, projectingdownward from the tube B, and encompassed by a tubular slider, II, connected to the slider F by a pin, d, that extends from one to the other of the two sliders and through a short slot, e, made in the tube G lengthwise thcreol". The said tube G is closed at its lower end by a cap, f, screwed upon it, and there is within the tube a spiral spring, g, for advancing the actuator, which is to be retracted by the hand of a person applied to the slider H, and drawing the slider downward in the tube G. Theslider F has fixed to it a wedge, I, provided with a stud, 11 of the width ot' and extended into the slot c. Ou retracting the slider F its wedge will be drawn between and against two projections, i i, ofthe notched bai-sl) D, and will force the bars apart sulliciently for the tube B to be moved lengthwise upon the tube A.

Having so moved the tube A the required dis-l tance, the slider F is next to be allowed to be advanced by the spiral spring g, which, in so moving the said slider, will cause it to correspondingly move the actuator between the two notched bars. The actuator is provided with triangular cams or projections ir, extending from its opposite edges into correspondinglyshaped notches i in the two bars D D, all being as represented. During an advance of the actuator its cams k operate in the notches so as to cause the two bars D to approach each other at their notched edges and close upon the head of the screw C, and thus hold the two tubes A and B locked together, from which it will be seen that the tube A can be moved lengthwise relatively to the tube B and tance.

rlhe brackets for holding the candles or lamps of the chandelier are to be attached to and project radially from a bowl, L, fixed to and encompassing the outer tube, B.

I claim, in an extension chandelier or lampholderlocked to it when adjusted to the proper dis- IOO 1. The combination ofthe tube A,having the stud or headed screw C, and the slotted tube B, with the jaws or strips D D, notched as set forth, and with mechanism for moving such jaws laterally toward and away from each other, to either engage them with or disengage them from the said stud or screw, all being substantially as set forth.

2. The combination, substantially as described, for operating the notched jaws D D within their tube, and so as to engage them with and disengage them from the stud or screw C, of the rod or tube A, such combination consisting of the neck G, with the spiral spring g, the connected sliders F and H, the r 5 wedge I, projections t' i, and notches l of the bars D D, and the actuator E, having the cams orprojections 7c 7c, all being arranged and to operate essentially as represented.
